As revenge for his rejection, he developed a shrink ray to miniaturize ships and began collecting various sea craft in bottles once they had been miniaturized. He came to the Turtles' notice when his machine was accidentally triggered by his cat Claude, and Michelangelo found himself miniaturized and trapped in a bottle. Breech was intrigued by the tiny turtle, and decided to keep him and his sailboard.

However, Breech's undoing came about when Michelangelo managed to steal a tiny plane and make contact with the other Turtles. They stormed into his home and fought the three robots he unleashed on them, and in the course of the fight he accidentally destroyed his own shrink ray, which restored all the ships to normal size. He himself was left dangling from one of the boats.

Trivia

He is extremely sensitive about his tiny stature.

He seems to be a scientific genius, since he not only created the shrink ray, but a trio of dangerous robots.
